The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.

It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.
